UNITED STATES PATENT OFFICE,

JAMES N, PEASE, OF PANAMA, N. Y., ASSIGNOB T() THE METROPOLITAN VASHINGMACHINE COMPANY, OF MIDDLEFIELD, CONNECTICUT.

wRlNclNe-MACHINE.

Specification forming part of Letters Patent No. 19,0413, dated July 25,1865.

To all lwhom it may concern Be it known that I, JAMES N. PEAsE, ofPanama, in the county of Chautauqua, in the State of NewYork, haveinvented certain new and useful Improvements in ClothesY\/'1-iiig ers;and the following is a full description thereof, and the accompanyingdrawings, forming part of this specitication, represent one of the bestforms of my machine.

Figure l is an end view. Fig. 2 is a section on the line S S in Fig. 3,and Fig. 3 is a front view.

Similar letters of reference indicate like parts in all the igures.

A is a rigid frame-work forked at the bottom to allow it to be placedupon a tub in the obvious manner.

B is the lower roller, and C the upper roller. These are made of rubber,secured upon shafts ot'iron,` and the shaft of each is formed with acrank at each end, the crank at one end standing at right angles to thecrank at the other end.

The crank B carries a connecting-rod, D', which is adapted to fit overand slide on the fixed rod A at the other end. The crank C carries aconnecting-rod, E', which is attached to the rod or connection D bythepivot c.

The lower roll, B, is turned by the large addil tional crank M in theordinary manner, and at each revolution the connectionsDand Eslideoutward and return on the rod A in the man.

ner which will be obvious.

The crank B2 on the end of the roll B opposite to B carries aconnection, D2, which at its other end slides on the fixed rod A2. Thecrank C2 carries the connection E2, which is hinged to the rod D2 by thepivot or rivet e2.

The upper roll, C, is adapted to rise and sink either in a directionstrictly vertical or more or less inclined or curved. It is preferableto means be introduced to compel it toy turn at the same rate as itsmate. Ordinary gearing does not well allow ot' the vertical motion ofthe roll C, because the gearing becomes disconnected; but my devicecompels both ,rolls to turn together and allows them to diverge andagain approach freely. The connections D' and D2, being moved outwardand inward on their respective slides A and A2, compel a correspondingmovement of the connections E and E2, aud consequently compel therevolution of the upper roll, C, at a proper rate, whether it bearsdirectly upon B or is con,- siderably elevated by treating a thick massof clothing. The cranks B and B2, being set quartering or in planes atright angles to each other, or thereabout, as practiced withllocomotives andthe like, allow one to be effective while the other is onthe deadpoint; so the rolls are always certainly and powerfullyconnected.

G is a stoutlever hinged at g. G2 is acorresponding lever hinged at g2to the framing A. The shaft of the Lipper roll, C, is carried in holesin these levers, as indicated.

H is a narrow bearing-piece.

l is a lever which stands above G', and which is adapted to press on thepiece H, so as to produce a sufficient pressure on the clothes passingthrough the rolls B C, there being corresponding levers and connectionson each side ot' the machine to press down both ends ofthe roll C.

The bolts J, lxed on the frame-work A, serve both as guides for thelevers Gr and G2 and as tulcrums for thelevers I. The nutsj, fitted tobe adjusted on the bolts J, press on the upper faces of the levers I,either directly or through suitable washers or bearing-pieces, and bybeing set atvarious heights by the obvious process of turningthemcorrespondingly affect the position of the fnlcrums ot the levers.Screwing down on the nutsjinduces a greaterpressure on the goods beingwrung, other thi-ugs being equal. v

K K are gear-Wheels mounted to mesh with the racks L L on the framing.The wheels K are lixed on the shaft 7c, which is carried in holes orbearings in the levers l, and may be partially turned by the hand-leverMi. ln operating my machine it is common to take hold the crank M withthe right and the lever M* i rolls, it being obviously proper to let theroll O rise when a thick article is being wrung and sink again withforce when it has passed and a thinner mass is being treated.

The operation ot' my gearing K and rocks L differs from cams which havebeen before used to contine the rolls of wringers, because cams aresubject to greater friction.' My levers I might, it' preferred, beconnected to the framing at L by a iexible strap of rubber belting orother suitable material adapted to roll around smooth wheels at K,instead ot' the gearing and racks, and l consider such an equivalent formy gearing and racks. Such devices, which are nearly i'rictionless,possess the quality ot' self-adj ustment when the weight of the levers Iis alone availed of to depress the upper roll, and in this respect aresuperior to cams, and they allow the hand ot' the operator to be appliedso soon as free from the duty ot' introducing a garment and to aid byits weight or by its positive action upward or downward in inducing theright action oi' the apparatus on the fabric or clothes being squeezed.When the machine is to receive a verythin setof articles-as ladies7collars-the screw-nuts j aie set down by the hand or by a suitable tool,and when to receive a thick lotas bed-blankets-these screwnuts should beturned in the opposite direction. In other Words, my levers l arehand-levers so arranged and combined that they may vbe also adjusted bythe nuts j, and that they are or tend to be self-acting, so as to pressby their own weight and the weightot' the hand upon the clothes, and torise automatically without care or i'orethought by the operator so soonas a thick portion ot' the goods comes into the rolls.

This portion of the invention may obviously be worked without theadjustment provided by the nuts j, or with far less scope for suchadjustment than is here provided. The movement of handlever Mis alone bythe will of the operator, in anticipation ot' a thick mass, orautomatically with the mobile weight of the hand when the mass isactually compressed, or partly by each, as by an active movement of thehand after the mass is struck, will provide for ordinary differences inthickness sufticiently; but it is for great variations in thickness veryimportant to provide the nuts j or some equivalent means of adjusting atthat point, in combination with the hand-lever ad justment, asdescribed.

The screw N is for attaching the machine to atub and releasing atpleasure; but the turning of a screw against a tub is liable -to defaceand abrade it. The shield P, turning or sliding on the pivot p, isadapted to receive the force of the screw N and transmit it withoutinjury. The slot in the shield where it embraces p is sufficient toallow such a sliding motion as compensa-tes for the usual difference inthe size ot' tubs, while the shield is free to move to a much greaterextent by swinging, so as to very readily slide down upon the tub to itsplace and then be very effectually tightened.

It is not absolutely necessary that the reciprocating ends of theconnecting-rods B', 8vo., shall slide on a rod so as to move inprecisely right line. A sufticient approximation thereto may be obtainedby providing a long link eX- tending either downward or-upward from thepoints ot'juncture e or c2, and pivoted to a fixed portion ot' theframing A. ln such case the reciprocating motion will be curvilinear,but it may be performed with less 'riction than on a slide, and it maybe made to operate successfully.

I believe my mode of communicating motion from one roll to the other tobe absolutely new in the arts in all the various applications whererolls or equivalent wheels, 85e., whether hard or soft, smooth ortoothed, are required to be turned toward each other. I propose toemploy my invention as above described for the feedmotion rolls ofplaning-machines, stavedressing machines, and other lumber and metalworking devices also in calendering, printing, drawing, and pressing forany and all purposes whatsoever where this motioni. e. rotation inopposite directionsis required.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is as follows:

l. The cranks B C and B2 C2 and rods D E and D2 E2, with suitable guidesfor the reciprocating ends of the connections, all arranged for jointoperation, so as to transmit the motion ot' one roll to the other,substantially as and for the purposes herein specified.

2. The gear K and rac/k L, or their equivalents, in combination with thehand-lever M* and with the movable roll C, adapted to be operate-d bythe weightofitselt and ofthe hand, substantially as herein specified.

3. The hand-lever Mtl, operating to depress one end of the lever I, incombination with the adjustingscrew-nutj orits equivalent, adapted topress upon and torm a movable fulcrum at the opposite end, substantiallyas herein specied.

et. The sliding and swinging shield-piece P, mounted and arrangedsubstantially as and for the purpose herein set forth.
